Item 8.01. Other Events.

On December 6, 2016, Heat Biologics, Inc. (the “Company”) issued a press release announcing topline response and survival results in its ongoing Phase 1b study evaluating HS-110 in combination with Bristol-Myers Squibb’s anti-PD-1 checkpoint inhibitor, nivolumab (Opdivo®) for the treatment of non-small cell lung cancer.  The Company reported that 1-year results from the first eight trial patients showed that the HS-110/nivolumab combination was well-tolerated with a safety profile consistent with single agent nivolumab. There were no additional toxicities seen in HS-110/nivolumab combination compared to existing data on single agent nivolumab alone.  HS-110 generated a robust antigen-specific immune response in several patients consistent with the mechanism of action seen in other HS-110 trials.  Additionally, the patients who responded best to the combination therapy (“immune responders”) had longer overall survival and better objective response rate (“ORR”) than the non-immune responders, even though they had the same baseline immune function. Immune responders in the study saw a 50% ORR while non-immune responders saw a 0% ORR. Moreover, the immune responders had a better median overall survival (“OS”) than non-immune responders.  The 1-year OS is currently 50% for the responders and 25% for the non-responders. Finally, immune responders also saw a better median OS at 12.7 months, than non-immune responders, who saw a median OS of 7.1 months.  Researchers concluded that immune response may correlate with clinical efficacy and that HS-110 may have synergistic activity with immune checkpoint inhibitors.
